That way, we don't have to guess what the toolchain does, but rather

Unfortunately we can't do the same thing on xtensa, as that no longer
supports the -mbig-endian/-mbig-endian flags in any recent gcc version
(a long time ago it had them, but they were removed along with many other
options).
For xtensa we probably need to generate Kconfig fragment that would go
in with the variant subdirectory. That will solve this, and clean up other
options that we currently have for manual selection for xtensa, but there's
actually no choice, i.e. the option has to be selected correctly, there's only
one correct choice and otherwise the kernel either won't build or won't work.
I'll look into it.
Max. Thanks. Please update us when you are done.
